摘要
采用玉米蛋白凝胶电泳法和田间小区种植鉴定法对30个杂交玉米种子样品进行纯度测定,并对2种方法所得数据进行了回归分析。结果表明,2种方法所得结果达显著相关,相关系数r=0.653 1,线性回归方程为:y=23.93+0.760 8x。证明蛋白质凝胶电泳法鉴定玉米种子纯度是可靠的,且可用电泳纯度推算出田间鉴定纯度。
The purities of 30 samples were identified by means of protein electrophoresis and field-planting. The results of two ways were distinct correlationship, the correlation index r=0.653 1, the regress formula was y=23.93＋0.760 8x. The results indicated that it is reliable to identify maize varietal purity by means of protein electrophoresis.
